Dockerfile Wizard is aimed at software developers who may not be super comfortable using Docker—you need a Docker Hub account, but don’t need Docker installed locally at all.
With it, you can build Docker images with particular versions of various common languages/dependencies/frameworks, all on CircleCI.
I like configuring my own from scratch, but I can certainly see the usefulness of a Dockerfile configurator.
I was pondering some months ago a simple web app that helps users write a Dockerfile, and irons out the awkward fiddle-factor by doing stuff that is already tested (e.g. if you’re installing Composer, then you’ll need php-openssl and git etc. It would just be a series of checkboxes, and would show the Dockerfile being dynamically written. That can then be pasted into a project and (in theory) Just Work.
